• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - hanh sinh cua ((nhung hong) OR (nhung huong)) van ((tuan ban) OR (luan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh sinh cua ((nhung hong) or (nhung huong)) van ((tuan ban) OR (luan ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh sinh cua ((nhung hong) or (nhung huong)) van ((tuan ban) OR (luan ban))*.
